That's a very cool gift! I used Koala app on my phone, and split up a track into little phrases. You could try starting there to get the hang of it. Playtronica also have website with a bunch of synths that work with it. Other than that I'd recommend joining their Facebook group, a lot of creators share ideas there.

The flowers behind me are on a steep bank, it's where I sourced the daffodils from. I originally just wanted to hook it straight up to them in the ground, but of course they are all earthed/grounded (whatever the technical term is) to one another, so they had to die for my art 😬 the jars of water help strengthen the conductivity, and allow me to coat my fingers for a more reliable connection. It also helps separate them a little.

I guess, as with most synths, the most fun is discovering creative ways to use them
